Patented Aug. 17, 1954 GREASE DISPENSING PAIL BASE Edwin P. Sundholm, Albert City, Iowa, assignor to Our Saviors Evangelical Lutheran Church, Albert City, Iowa, a corporation of Iowa I Application July 24, 1947, Serial No. '763,225

6 Claims.

The present invention relates to certain new and useful grease-gun-loading pail-base or pump-loading pail-base, for receiving, at its top, an original and relatively thin-walled and inexpensive vendable merchandising container (namely, a container in which the fluid or semiluid is originally packed, shipped, stored and sold), as, for instance, an original thin-walled sheet-metal pail of lubricant (such as grease or viscous oil) or of printers ink, caulking compound, etc., and for receiving, at its side, the reservoir-barrel of a grease-gun or the like or a pump-cylinder, whereby the lubricant or other viscous iluidmay be conveniently loaded directly from the original container into the reservoirbarrel of the grease-gun or into the pump-cylinder through the intervention of the gun-loading pail-base of thepresent invention.

One of the further objects of the present invention is to provide a gun-loading pail-base or transfer-base whichwill be adapted to `receive and operatively to engage a pail with a standard bottom flange with a standard seam-bead, and without any special bayonet lugs or projections.`

One of the objects of the present invention is to permit the use of a more or less standard or conventional pail rather than requiring a special pail; i l u Other objects of the present invention will appear from `the following description and the accompanying drawings, wherein I have shown, for the purpose `of illustrating my invention, forms thereof which `are at present preferred, although it is to be understood that the various instrumentalities of which the invention consists can be variously arranged and organized and that the invention is not limited to the precise arrangements and organizations of the instrumentalities as herein shown and described.

In the accompanying drawings, in which like reference characters indicate like parts,

Figure 1 represents a cross-sectional view of the pail-base with a pail engaged therewith and a greasefgun connected thereto.` I l Figure `2 represents a top plan view ofthe same pail-base as shown in Figure 1, but on a smaller scale, 1and is intended merely to indicate the circumferential distribution of the `can-gripping means. i 1

r Figure 3 `represents afragmentary perspective view of a portion of oneoflthe can-gripping jaws of the form of construction indicated intFigure 1.

Figurer 4 represents `a fragmentary vertical cross-sectional view of one of the can-gripping means in the base of the form -offconstruction indicated in Figure 1, but on a somewhat larger scale.

Figure 5 represents a similar fragmentary topplan View on a similarly enlarged scale.

Figure 6 represents a fragmentary perspective view of the canegripping jaw of a modified or alternative construction.

Figure 7 represents a fragmentary vertical cross-sectional View of the can-gripping jaw of a modified form of construction represented by Figure 6. V

Figure 8 represents a fragmentary top plan view of the pail-base (without the can-gripping jaw) of the form of construction represented by Figure '7. l

In the drawings, `the pail or can is generally designated by the letter C, while the base is generally designated by the letter B.

The bottom I I-a of` the containerC, .is provided with a downwardly depending more or less cylindrical angelike portion Il-b, which telescopes into the lower end of the cylindrical body Il-d of the container C, to a greater or lesser extent, depending upon the axial length of ange |I-b, and is secured thereto by an interlocking crimped seam I I. l i

The sheet-metal bottom |I a, of the container C, may have pressed into it, in a downward direction (or in an upward direction), an annular groove 2,3, to form a doughnut-like ridge or annulus on the outside (or on the inside) of the bottom lI-a; the outer (or inner) moreor less dat or rounded annuluslikesurface 24 of which r constitutes a seating-surface for making sealingcontact with an annular sealing-gasket or ring 25 (of cork, grease-resistant rubber or composition or other suitable resilient material) carried by the base B. The annulus 23 is preferably centered, or approximately centered, `in relation to the periphery of the bottom Il-a of the container C. i i l,

The annulus 23 .also serves to stiiien the4 center of the bottom lL-a, `so that a circular discflike portion, within the center of the annulus 23, canV be more readily cut out orxknocked out` by the cutting action of the cutters (as in the embodiment herein shown and described) or by any other suitable disc-removal operation. 'Ihe ane nulusi23 also serves to center :or guide the cutters or knives 26, during the cutting operationandV serves also to stiffen and reinforce thercenter; o'f thebottom II-a after the dischas been cut out or removed therefrom` l c p In oneembodiment of the` base of my presentinvention, illustrated in .thedrawingsp athe` base B may be formed of two members 22-a and 22-b, which may be welded to each other or may be interlocked by a seam 29, so as to form a generally unitary construction, in which each member supports and gives rigidity to the other, thereby permitting the two members to be formed (by pressing between dies or by spinning or by rolling, or the like) out of relatively thin sheet-steel as, forY instance, 20 or 227.gauge sheet-steel for a base for a 25 lb. container, or other relatively thin sheet-metal, Yand yet maintaining adequate strength and rigidity in the nnished base B,

In the end-wall or bottom 22, a center aperture 3l is formed, and the material from the Y aperture 3| may be pressed or drawn upwardly to form a.4 short upstanding tube-like cuttersupporting intake-flange or intake member Si?,

although this tube-like cutter-supporting intakeange or intake member is preferably formed separately, asshown, in the drawings, and spotmetal around the hole 3l may be pressed down in a downwardly extendingannulus 33, :forming an annular groove around the tube-like flange 32, for thefreception and retention of the resilient andY g-reaseeresistant packing-gasket or sealingring 25,

.From the partition-wall or bottom 22,V a

radial channel 3,4, of more or less U-shaped crossthe annulus 23 thereof,y outwardly to the gunreceiving socket 35 formed inor ainxed to the side of the base BJ Y In'the'top'. wall 22 of the base fB, which may be either of .the'tWo-.ply construction shown in 4 In form of construction shown in Figures l, 3, 4 and 5, this latter means may be in the form of'a pair of wing-like lugs 6 bent or pressed from the vertical portion 5 of the member l, and out of the plane thereof; these projections S bearing against the top of the base and serving to prevent member I from moving down Vinto the base beyond the point indicated in Figures l and 4.

'A helical compression spring 1 is interposed .between the lower and more or less horizontal portion ll of the member i and the under side or the top of the base 22. To keep 'the spring I Y safely in place, the cup-like vsockets or springseats 8 and 9 may be pressed into the portion l and into the top 22, respectively, asV shown in Y Figures 4 and 7. Y

The spring l urges the lower portion 4 of the l Y bead-gripping member I downwardly, and as this Vweldedor crimpgseamed to the aperture 3 I. The

member is pivoted loosely in the slot 3, the upper portion .5 thereof is moved radially inwardly in the direction of the arrow ig, lThis causes the claw 2 to engage above the laterally projecting bead il of the pail orV can (2, in the,V manner indicated in Figure '1. Y

The uppermost portion i2 oi the bead-grinning member Yl is preferably bent outwardly slightly, as indicated in Figures l and 2,` so that by pressing more or less downwardly'and upwardly on the molines., tab. l2, the upper .portion 5;, together with the slew 2, een loe mede to move upwardly slightly against the force of the .spring liso as to` release. its erin omer engagement from, the bead H. of the peil or eau C.. The tab i2 may be engaged br hond. or; by simply pressing. downen it with the foot. ofthe operator, t Y

In the form of construction illustrated in Ei'gl. ures 1,13, 4 andv 5, the slits or slots '3 mayeach be plain slitsor. slots4 of uniform width, throughout. `.Each bead-.gripping member I is, formed with l the` lowerI portion 4, which extends into the interiorifoftheJba'se'B. through the'. slot 3, and the outer portion 5.which extends above base B, and
